We are offering hydrolyzed collagen. cas no.: 92113-31-0assay: 90% of the protein contentpacking: 20kg/barrelspecification: food standarduses: the hydrolysis of collagen by enzymatic collagen molecules hydroxylation complex spiral state can easily break down small molecule peptide structure, molecular weight of less than 3000 daltons. After enzymatic conversion collagen very easily absorbed by the body can greatly improve its bioavailability.
